I-ZDM Series I-valve yokulawula ukujikeleza kabusha okuzenzakalelayo
Uchungechunge lwe-ZDM I-valve ye-recirculation ezenzakalelayo iwuhlobo lwedivayisi yokuvikela iphampu. Ivikela ngokuzenzakalelayo iphampu ye-centrifugal lapho umzimba wepompo kwenzeka umonakalo we-cavitation noma ungaqiniseki (ikakhulukazi ukudlulisa amanzi ashisayo ekusebenzeni komthwalo ophansi). Uma ukugeleza kwepompo sekuphansi kunokugeleza okusethiwe, i-bypass ingavuleka ngokuphelele ukuze kuqinisekiswe ubuncane bephampu yokugeleza edingekayo. Ngisho nokusebenza kuvaliwe ngokuphelele, okungukuthi ukugeleza okusebenzayo kunguziro, ukugeleza okuncane kungaphinda kudlule ukuze kuphindwe ku-Automatic. Ukucindezela kuncishisiwe nge-valve yokunciphisa ingcindezi ye-bypass multistage.
Uchungechunge lwe-ZDM lufanele ukudlula ngokuhluka kwengcindezi ephezulu, umehluko omkhulu wengcindezi ngu-30MPa, futhi ukukhetha okuthile kunqunywa ifektri. I-Multistage decompression uhlobo lwe-bypass yohlobo lwe-M lungaqeda umsindo owenziwe yi-high-speed flow medium, ivimbele ukulimala kokuguguleka kwe-cavitation kanye ne-braising ezingxenyeni ze-valve.
• Vimbela i-cavitation multistage decompression bypass, ukunciphisa isivinini, kufanelekile izimo zokucindezela okuphezulu.
• Umzimba we-valve owakhiwe, noma ungakhetha i-carbon steel noma impahla yensimbi engagqwali, njll.
• Umsebenzi wokudlula ojwayelekile ongabuyi, umehluko omkhulu wengcindezi yokusebenza ngu-30MPa.
• Ibanga lokucindezela ukusuka ku-PN16 ukuya ku-PN420, ububanzi ukusuka ku-DN2 ukuya ku-DN500.
• Ingakhetha umsebenzi wokusebenza ngokudlula ngesandla, osetshenziswe iphutha.
Uhlobo lomzimba we-valve: I-valve eyakhiwe ngezindlela ezintathu
Ububanzi bokuzisholo: NPS1"-20" (DN25, 32, 40, 50, 65, 80, 100, 200, 250, 300, 350, 400, 450, 500)
Ingcindezi encane: CL150#-2500# (PN16, 25, 40, 64, 100, 160, 250, 420)
Uhlobo lokuxhumana lokugcina: I-Flange, FF, RF, RTJ, BW, SW njll.
Ngokomehluko wokugeleza okuyinhloko kwe-inductive, ikhoni yokuhlola idiski ye-valve ezenzakalelayo ye-automatic recirculation valve izohamba ngokuzenzakalelayo endaweni ethile. Ngaso leso sikhathi isiqu se-valve ye-valve eyinhloko, dlulisa ukunyakaza kwe-disc ye-valve enkulu ukuze udlule, ngokulawula indawo ye-valve ye-disc, shintsha indawo ye-bypass throttling, ukuze ulawule ukugeleza kwe-bypass. Uma i-disc ye-valve eyinhloko ibuyela esihlalweni se-valve ivaliwe, wonke ageleza abuyele emuva adlule ngokudlula. Lapho i-disc ye-valve eyinhloko ikhuphukela endaweni ephezulu, i-bypass ivalwe ngokugcwele, konke ukugeleza kwepompo ukugeleza ohlelweni lokucubungula. Le valve ibeka imisebenzi emine emzimbeni owodwa.
• Umbono wokugeleza: I-automatic valve recircution main valve disc ingabona ngokuzenzakalelayo ukugeleza okuyinhloko kwesistimu yenqubo, ngaleyo ndlela ngokuvumelana nokugeleza kokunquma indawo yediski ye-valve eyinhloko kanye ne-bypass disc.
• Ukulawula ukujikeleza kabusha: Ivalvu yokujikeleza kabusha okuzenzakalelayo ingakwazi ukuhogela ukusebenza kwephampu evamile edingekayo ukugeleza okuncane kusisetshenziswa sesitoreji ngokudlula, ukuze kulungiswe izici zephampu ye-HQ, ukuze kuqashwe kabusha.
• Ukunciphisa umfutho we-Bypass multistage: isistimu yokulawula i-bypass inganciphisa i-backflow medium ukusuka endaweni yepompo yokucindezela okuphezulu ukuya ekuphumeni okufanelekile kuya kudivayisi yokugcina ingcindezi ephansi enomsindo ophansi ukuguga okuncane.
• Hlola: I-automatic recirculation valve nayo inomphumela we-valve wokuhlola, ukuvimbela uketshezi olubuyela emuva ukuze lumpompe umzimba. Umsebenzi wokudlula ongabuyi ujwayelekile.
• Usayizi wokudlula okhethekile ungenziwa ngokwezifiso. Izinga lokugeleza elikhulu lokudlula lingaphansi kwevelu enkulu ye-Kv.
